I have been looking at either an S60 or S80, years 2006 or 2007. I am looking for the real life mpg for highway and city driving? Also what grade of gasoline is required? What are the approximate costs of maintenance? I will keep a car for at least 180,000 miles. The present car that I have has reached that number.
Thanks,
Rick

 

It really comes down to just a question of do you want the slightly larger S80 or the smaller S60. Read up on both in the S60 and S80 forums. Gas mileage should be similar on either, but probably a little better on the S60 as it is lighter.
